If a woman's uncle has Lesch-Nyhan syndrome and her father carries the mutation, the probability of her first son being affected is 50%.
Lesch-Nyhan syndrome is an X-linked recessive genetic disorder, which means it is caused by a mutation on the X chromosome and is passed down through families primarily from affected fathers to their daughters. The probability that a son of a woman with an affected uncle (mother's brother) will be affected depends on the genetic status of the woman's father and the mother's X chromosome that she inherited from her mother.
If the woman's father does not carry the mutation, she will not carry the mutation herself and cannot pass it on to her children. In this case, the probability of her first son being affected is 0%.
If the woman's father carries the mutation, she has a 50% chance of inheriting the mutated X chromosome from her father and a 50% chance of inheriting a normal X chromosome from her mother. In this case, if the woman is a carrier of the mutation, her first son has a 50% chance of inheriting the mutation from her and being affected.
It's important to note that this is a simplified answer and that more complex genetic testing and counseling may be necessary to determine the specific risk in a particular family.

T=8, 1=$7140, R = 0.17
P= $ (Simplify your answer.)
Using the formula of Interest I = PRT and given values the value of P is $5250.
What is Interest?Interest is the sum over and above the original amount (the amount borrowed) that is paid to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. Interest differs from profit, in that interest is received by a lender, whereas profit is received by the owner of an asset, investment or enterprise.
Given that, the formula is I = PRT
I = $7140, R = 0.17, T = 8
To find the value of P, from the formula
7140 = P * 0.17 * 8
⇒ 7140 = P * 1.36
divide both sides with 1.36 we get
⇒ 7140/1.36 = P
⇒ P = $5,250

of an Atlas rocket at a point 800 meters from the launch
pad. Let 0 be the angle of elevation to the rocket and let
s be the height of the rocket. Find 0 when s = 1500 meters.
Answer:
Step-by-step explanation:
Use SOH CAH TOA.
Using TOA or tangent = tan0 = opp/adj.
tan0 = 1500m/800m -> tan0 = 1.875
Use inverse tan or tan^-1.
0 = tan^-1(1.875)

what is the probability that at least two of the faces match when you roll three fair six-sided dice? express your answer as a common fraction.
The probability that we get the same faces when we roll 3 fair six-faced dice is 44.44%.
What is probability?Simply put, the probability is the likelihood that something will occur.
We can discuss the likelihood of several outcomes or the potential of one outcome when we are unsure of how something will turn out.
Statistics is the study of events that fall into a probability distribution.
Therefore, there is a chance that each one is unique:
6/6 * 5/6 * 4/6 = 120/216
Therefore, the likelihood that at least two of them will display the same face is:
1 - 120/216 = 96 / 216 =44.44%
Therefore, the probability that we get the same faces when we roll 3 fair six-faced dice is 44.44%.

Which angle measure is equivalent to 144°?
The price for calculating the price to deliver a parcel of mass m kg is price ($) = 7 + 3.5m
What is the mass, in kg, of a parcel with a delivery price of $70?
Answer:
18 Kg
Step-by-step explanation:
We can use algebra to solve for the mass, m, given the delivery price, $70.
Starting with the formula:
price ($) = 7 + 3.5m
We can substitute $70 for price ($) and solve for m:
$70 = 7 + 3.5m
Subtracting 7 from both sides:
$63 = 3.5m
Dividing both sides by 3.5:
m = 18
Therefore, the mass of the parcel is 18 kg.

The simplified expression of 1+sin^2-cos^x / 2sin^2x issin^2(x) / 2(1 + cos(x)) + 1 / 2(1 - cos(x))
What is the simplified expressionTo simplify this expression, we can first simplify the numerator by combining the terms inside the parentheses:
1 + sin^2(x) - cos(x) = sin^2(x) + 1 - cos(x)
Next, we can factor the denominator trigonometric identity sin^2(x) + cos^2(x) = 1:
2 sin^2(x) = 2(1 - cos^2(x)) = 2 - 2cos^2(x)
Now we can substitute these simplified expressions into the original expression:
(1 + sin^2(x) - cos(x)) / (2 sin^2(x))
= (sin^2(x) + 1 - cos(x)) / (2 - 2cos^2(x))
= [(1 - cos(x)) + sin^2(x)] / [2(1 - cos(x))(1 + cos(x))]

A fish swims a distance of 6 km in 5 minutes. What is the average speed in m/s
Answer:
Step-by-step explanation:
6 km = 6000 m
5 min = 300 s
6000m / 300s = 20 m/s
Answer:
20 m/s
Step-by-step explanation:
The average speed of the fish can be calculated by dividing the distance traveled by the time taken.
First, we need to convert the distance from km to meters:
6 km = 6,000 meters
Next, we need to convert the time from minutes to seconds:
5 minutes = 5 × 60 = 300 seconds
Finally, we divide the distance traveled by the time taken:
Average speed = 6000 meters / 300 seconds = 20 m/s
So, the average speed of the fish is 20 m/s.

The wave amplitude was A = 15849 Ao times stronger the wave amplitude of the earthquake was than Ao.
How to solve for the waveThe formula to solve this is given as
K = log (A / Ao)
Where we have k to be the constant that is measured on the richter scale as 4.2
Then when we put this in the formula, we would have:
4.2 = log (A / Ao)
